Title
(EN) WIRELESS COMMUNICATION SYSTEM AND TERMINAL-DEVICE AUTHENTICATION METHOD IN WIRELESS COMMUNICATION SYSTEM
(FR) SYSTÈME DE COMMUNICATION SANS FIL ET PROCÉDÉ D'AUTHENTIFICATION DE DISPOSITIF TERMINAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract
(EN)
A wireless communication system includes code transmitters (20a, 20b) each configured to transmit a time-varying code; code receivers (30a, 30b) each configured to receive the time-varying codes transmitted from the code transmitters (20a, 20b) and generate a fingerprint based on the received time-varying codes, the fingerprint being unique to a space where the time-varying codes are receivable; and terminal devices (40a, 40b) configured to establish wireless communication connection therebetween with authentication. The terminal devices (40a, 40b) are connected to the code receivers (30a, 30b), respectively. Each terminal device (40a, 40b) includes a fingerprint acquiring unit configured to acquire the fingerprint from the code receiver (30a, 30b), a wireless communication unit configured to transmit and receive the fingerprint via wireless communication, and an authentication unit configured to authenticate another terminal device if the fingerprint received from the another terminal device matches the fingerprint acquired from the code receiver connected thereto.

L'invention concerne un système de communication sans fil qui comprend des émetteurs de code (20a, 20b) configurés chacun pour émettre un code temporellement variable ; des récepteurs de code (30a, 30b) configurés chacun pour recevoir les codes temporellement variables émis par les émetteurs de code (20a, 20b) et générer une empreinte numérique sur la base des codes temporellement variables reçus, l'empreinte numérique étant propre à un espace dans lequel les codes temporellement variables peuvent être reçus ; et des dispositifs terminaux (40a, 40b) configurés pour établir une connexion de communication sans fil entre eux avec authentification. Les dispositifs terminaux (40a, 40b) sont connectés aux récepteurs de code (30a, 30b) respectivement. Chaque dispositif terminal (40a, 40b) comprend une unité d'acquisition d'empreinte numérique configurée pour acquérir l'empreinte numérique auprès du récepteur de code (30a, 30b), une unité de communication sans fil configurée pour envoyer et recevoir l'empreinte numérique par communication sans fil, et une unité d'authentification configurée pour authentifier un autre dispositif terminal si l'empreinte numérique reçue de l'autre dispositif terminal correspond à l'empreinte numérique acquise auprès du récepteur de code auquel il est connecté.
